how to do a simple exprmnt or exmpl of daily life phenomenan about purification metal in industry by elctryls?
This is actually the refining process for copper. Impure copper recovered by other means is purified by electrorefining where it serves as an anode in an electrolyte containing copper ions (usually a copper sulfate solution). The cathode is a pure thin plate of copper – called a starter-sheet. The reactions are: Anode Cu(s) Cu++ + 2e- Cathode Cu++ + 2e- Cu(s)
